| description | The invention relates to a preparation method of a filtering material with removal effect on heavy metals in water and soil. The preparation method comprises the following steps: (1) grinding attapulgite clay into a 200-mesh powdery body, firstly adding 1-5% of 200-mesh aluminum phosphate according to weight percentage, then adding 1-5% of wood shavings according to weight percentage, and evenly mixing; (2) evenly adding the mixture into a granulator, atomizing to add water, mixing, and processing the mixture to be spherulitic; and (3) using an air dry oven for constant-temperature drying for 3-6h at 60-70 DEG C, and after drying, using a digital display shuttle kiln for firing the mixture into a pottery-shaped body at the temperature of 400-800 DEG C. The preparation method has the advantages that raw materials are cheap and can be obtained easily, the preparation method is simple and can be easily controlled, and the obtained filtering material has high adsorption capacity for manganese, is good in stabilit |
